The factors that shape the distinctive tumor-immune landscapes of various types and subtypes of cancer remain poorly understood. In this issue of Immunity, Mollaoglu et al. (2018) reveal a mechanistic link between the function of lineage specifiers SOX2 and NKX2-1 and the presence of neutrophils in the tumor-immune microenvironment of lung cancer.

Methotrexate (MTX), an antimetabolite targeting certain autoimmune conditions and various hematologic malignancies, has been associated with iatrogenic lymphoproliferative disease (LPD) primarily of B-cell lineage. Less commonly are T-cell neoplasms where primary skin involvement is considered rare. Three cases were encountered in the medical practice of one of the authors.

Pioneering work in the chicken established that the initial development of the heart consists of two stages: the quick assembly of a beating heart, followed by the recruitment of cells from adjacent tissues to deliver the mature in-and outflow tract. Cells to build the primitive heart were dubbed the first heart field (FHF) cells, cells to be recruited later the second heart field (SHF) cells. The current view is that these cells represent distinct, maybe even pre-determined lineages.

Despite being a major target of reconstructive surgery, development of the ear pinna remains poorly studied. Here we provide a cellular characterization of late gestational and postnatal ear pinna development in two rodents and investigate the role of BMP5 in expansion and differentiation of auricular elastic cartilage. We find that ear pinna development is largely conserved between Mus musculus and the highly regenerative Acomys dimidiatus.

Stomatal abundance sets plants' potential for gas exchange, impacting photosynthesis and transpiration and, thus, plant survival and growth. Stomata originate from cell lineages initiated by asymmetric divisions of protodermal cells, producing meristemoids that develop into guard cell pairs. The transcription factors SPEECHLESS, MUTE, and FAMA are essential for stomatal lineage development, sequentially driving cell division and differentiation events.

Development of multicellular organisms requires well-orchestrated interplay between cell-intrinsic transcription factors and cell-cell signaling. One set of highly conserved transcription factors that plays diverse roles in development is the SoxC group. C.
